Saamaynta nadiifinta eemishiinka qarxinta rasaastawaxaa lagu tijaabin karaa hababka soo socda:
1. Kormeer muuqaal ah:
Si toos ah u fiirso dusha sare ee qalabka shaqada si aad u hubiso in wasakhda sida miisaanka, miridhka, wasakhda, iwm. laga saaray iyo in dushu gaadhay nadaafaddii la filayey.
Hubi qallafsanaanta dusha shaqada si aad u go'aamiso in ay buuxisay shuruudaha.
2. Ogaanshaha nadaafadda dusha sare:
Isticmaal habka muunada isbarbardhigga si aad u barbar dhigto dusha shaqada ee la daweeyay iyo muunadda nadaafadda caadiga ah si aad u qiimeyso nadaafadda.
U fiirso xaaladda microscopic ee dusha shaqada adigoo kaashanaya muraayad weyneynaya ama mikroskoob si loo go'aamiyo wasakhda haraaga ah.
3. Ogaanshaha qallafsanaanta:
Isticmaal tijaabiyaha qallafsanaanta si aad u cabbirto cabbirrada qallafsanaanta ee dusha shaqada, sida Ra (macnaha xisaabinta ee profile), Rz (dhererka ugu sarreeya ee profile), iwm.
4. Ogaanshaha walaaca haraaga ah:
Cabbir walaaca hadhaaga ah ee dusha sare ee workpiece ka dib markii shot qarxinta by habka raajada diffraction, habka dalool indha la'aan iyo hababka kale si ay u qiimeeyaan saamaynta qaraxa rasaas on waxqabadka workpiece ah.
5. Tijaabada adhesionka ee dahaarka:
daahan waxaa laga codsadaa on dusha workpiece ka dib markii rasaas qarxinta, ka dibna xabagta daahan ayaa la tijaabiyaa, taas oo si dadban ka tarjumaysa saamaynta ay ku rasaas qarax nadiifinta saamaynta on adhesion daahan.
